Abstract
The invention discloses a wind indicator, and relates to a wind power generation wind indicator. The wind indicator comprises a wind vane and a rotating head driven by the wind vane to rotate; a protective cover is arranged on the rotating head, and is perpendicular to the wind vane; a heating device is arranged on the protective cover, and adopts a heater strip. Through the technical scheme that the heating device is arranged on the protective cover, the protective cover is taken as a guidance to quickly transmit heat to the wind vane and a rotating cover of the wind indicator, the problem that as the rotating cover and the wind vane of the wind indicator are easily frozen under the low temperature freezing environment, the wind indicator does not work is solved effectively. Meanwhile, the protective cover prevents sand, so that the rotating head is prevented from being blocked by sand.
Description
Technical field
The present invention relates to a kind of flow direction vane, particularly a kind of wind-power electricity generation flow direction vane.
Background technique
Fig. 1 is traditional flow direction vane, and this flow direction vane is comprised of wind vane 2, swivel head 1, support body 3 and base 4.Wind makes wind vane 2 point to the direction of wind regimes, thereby and the bearing 16 of driven rotary 1 code-disc be connected with bearing 16 17 occurrence positions are changed, the wind vane header 21 of bearing 16 and wind vane 2 is connected by fixing bolt 12.And by number of degrees device 18, calculate the position that code-disc moves, the concrete direction of judgement wind, sectional drawing as shown in Figure 2.Simultaneously, on support body 3, add and have powerful heating wire 30, avoid because of under the environment of cryogenic freezing, on the rotary cover 15 of flow direction vane and wind vane 2, easily generation is freezing, causes not working.But due to the bearing of flow direction vane inside and the existence of other structures, the heat of heating wire is difficult to be delivered on wind vane 2 and rotary cover 15, causes wind vane 2 to be easy to not work.And flow direction vane uses through long-time, swivel head 1 is easily stopped up by dust storm, and bearing 16 also will produce wearing and tearing, and the generation of wearing and tearing will cause the Product Precision skew, and finally causes flow direction vane to work.
Summary of the invention
The purpose of invention is for wind vane and the rotary cover that solves flow direction vane easily is frozen, swivel head is blocked and bearing produces the problem of wearing and tearing through long-time use.
Summary of the invention: in order to achieve the above object, the invention provides a kind of flow direction vane, comprising: wind vane and by the swivel head of wind vane driven rotary, and on swivel head, be provided with a protective cover, this protective cover is vertical with wind vane to be arranged.
Further, on described protective cover, be provided with heating equipment;
Further, at described heating equipment, be heating wire.
Beneficial effect: by heating equipment is arranged on protective cover; using protective cover as conduction; rapidly heat is delivered on the wind vane and rotary cover of flow direction vane; effectively avoid because of under the environment of cryogenic freezing; on the rotary cover of flow direction vane and wind vane, easily occur freezing, and not working of causing.Meanwhile, protective cover also will protect dust storm, avoid swivel head to be stopped up by dust storm.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiments only is not used in and limits the scope of the invention be used to the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
The present invention improves on the basis of the structure of existing flow direction vane, from the different of prior art, be the protective cover that has increased swivel head, and the heat conductive filament is placed on protective cover.Be illustrated in figure 3 the stereogram of flow direction vane of the present invention, flow direction vane 100 comprises: wind vane 2, by the swivel head 1 of wind vane driven rotary, form in order to support body 3 and the base 4 supported.Shell at swivel head 1 increases protective cover 10; protective cover 10 setting vertical with wind vane 2; protective cover extends to the medium position of support body 3 always; protective cover 10 and support body 3 can be fixed connection by riveted joint or welding manner; on protective cover, be provided with heating equipment 31 near on the position of support body 3, this heating equipment 31 is generally powerful heating wire.By heating equipment 31 is arranged on protective cover 10; using protective cover as conduction, heat is delivered on wind vane 2 and rotary cover 15 rapidly, effectively avoid because of under the environment of cryogenic freezing; on the rotary cover 15 of flow direction vane and wind vane 2, easily occur freezing, and not working of causing.Simultaneously, protective cover 10 is also protected swivel head 1, avoids being stopped up by dust storm.
In this simultaneously, the increase of protective cover 10, will make the flow direction vane of the present invention can only half-twist, make measuring range dwindle.When change of the wind was certain numerical value, during such as+124 °, 45 ° of wind vane postive direction rotations, due to the existence that protective cover 10 is arranged, can only rotate 45 °.Flow direction vane 100 is transferred to wind power generator control system to test result, and under control system was handled, blade 20 started 45 ° of rotations of postive direction.Meanwhile be arranged on the flow direction vane 100 45 ° of rotations of postive direction together on blower fan, as shown in Figure 5.And start new one and take turns the wind direction test.Test result remains 45 ° naturally, and after flow direction vane 100 test results were transferred to control system, fan blade 20 continued 45 ° of rotations.In this while flow direction vane 100, start for the third time to measure, and obtain a result 34 °, fan blade 20 rotates 34 ° simultaneously, and finally completes the control of 124 ° of rotations.Above whole process is actually continuous and continual.Do not affect the normal operation of wind-driven generator.By this mode, improved very easily existing product, can greatly avoid the work of swivel bearing, and improve the flow direction vane operating life.Meanwhile, in the present invention ± 90 ° just as one with reference to the number of degrees.In actual using process, even can be set as ± 10 °.
